You're the one who introduced voting records alongside a useless stat to try and make it a "both sides bad" argument. I'm simply showing you that the more correct way of using the stats demonstrate it to overwhelmingly be a problem of right wing states.
Thirty eight percent of white adults view gun violence as a big problem vs. sixty percent of Hispanic adults and an overwhelming 82% of Black adults (source: Pee Center) who overwhelmingly voted for Biden. It is a ‘national epidemic’ and while gun laws vary from state to state guns as a whole are a problem coast to coast.
